59 · 8 weeks is 56 days, plus 3 gives 59 days.
205 · 3 hours is 180 minutes, plus 25 gives 205 minutes.
60 · 1 hour always equals 60 minutes.
True · 2 minutes equals 120 seconds, and 150 seconds is greater than 120.
5 minutes · 300 / 60 = 5 minutes.
165 · 2 hours is 120 minutes, plus 45 gives 165 minutes.
2 minutes 30 seconds · 120 seconds make 2 minutes with 30 left over: 2 minutes 30 seconds.
59 · 8 × 7 = 56, plus 3 more days makes 59.
2 minutes 5 seconds · 125 ÷ 60 = 2 remainder 5, so it's 2 minutes and 5 seconds. Seconds can never go past 59.
He forgot to multiply the hours by 60 first · Hours must become minutes first: 2 × 60 = 120, plus 10 = 130 minutes.
